As indicated in Fig. 2, the shaft 11 is tubular and carries in its bore a tube 16 of insulating ,inateriah for example fibre,` hard rubber, balrelite vor similar material which tightly 4engages the bore of the shattto be carried thereby. The insulating tube 16 has inountedin one of its ends, a contact 17 comprising a.V metal body portion boied at its inner end to receive a contact making stud 18, which stud at its .end within the body portion 17,'.is provided with an enlarged head engaging aspring 19 tending to hold the stud in its outermost position. The body portion 17 has formed transversely thcrethroughan aperture 20 in lineA with. corresponding aper- 1 i tures through the shaft 11 andthe insulatingv tube 16 to receive one of the wires 21 of :the l conductor .15, said wire `21 being rigidly clamped to the body portion of the contact-17 j by means of abinding screw `22threaded inl 'Kto .the youter end of the contact 17.

The lother end of the*insulating*V tube 16 is internally threaded-to engage corresponding threads on a secondcontact 23 which extends at`its left hand end as'shownl in .2, be-

yond the said shaft andinsulating tube and terminates in :an enlarged head 23a. A wire 21 is-rigidly secured to the head l23a by nie-ans ot a clamping screw 25, the other `end of said wire being connected .with an insulated binding post 2G carried by :in extension 10 of the support 10. The screw 25 also rigidly secures tothe contact 23 an;arni 27 having an aperture .28 therethrough through which a rod 29 carried bythe extension 10 projects with a. sliding tit and in a. direction substantially vparallel with the axis of the shaft 11. Electric Contact between the contact 23 land the extension 10 is prevented to maintainy the wire 24 in insulated condition from the Vextension10a and Support 10, for example. by forming the arm 2i' and rod 29 ot metal,

and bushing the aperture 28 with insulating material as indicated. .This insulation of thel wire 211 and Contact 23from the ,extension 10a may rbe*accomplished by constructing` the arm 29 inany other desired manner and of any material ,that will prevent electric connection between said contact and saidextension.
